How do the general methods for separating mixtures and compounds differ

Answers

In a mixture, elements are not chemically reacted. The elements forming a mixture can be separated by physical methods. These methods include titration, boiling, filtration and so on.

On the other hand, compounds are formed by the chemical combination of two or more elements. This means that the elements forming the compound cannot be separated by physical means . A chemical reaction must be used to separate the elements forming a compound.

Final answer:

Separation of compounds requires chemical methods because of the chemical bonds between elements, while mixtures can be separated through physical methods due to the absence of chemical bonding between components.

Explanation:

The methods for separating compounds and mixtures differ mainly based on the nature of the materials in question. Compounds have definite compositions with chemical bonds between the elements and can only be separated into their elements using chemical methods such as electrolysis. On the other hand, mixtures are physical blends without chemical bonding. They can be separated into their components using physical methods like filtration, distillation, and crystallization. For example, a heterogeneous mixture like salt mixed with pepper can be separated through simple manual methods like sorting, while a homogeneous mixture (solution) like sugar dissolved in water may require distillation to separate the sugar from the water.

Why is a sodium potassium pump called an electrogenic?

Answers

Hey there.
Sodium potassium pump is called an electrogenic as it pumps ions out of the cell. 

Hope this helps :))

~Top
Final answer:

A sodium potassium pump is called electrogenic because it contributes to the creation of an electrical charge difference across the cell membrane. This is done by moving three sodium ions out of the cell and two potassium ions into the cell during each pumping cycle, leading to a net positive charge outside of the cell.

Explanation:

A sodium potassium pump is called electrogenic because it helps to create an electrical gradient or difference in charge across the cell membrane. This is due to its ability to move three sodium ions out of the cell for every two potassium ions it brings into the cell during each cycle of its operation. By so doing, it causes a net positive charge to accumulate outside the cell relative to the inside, leading to an electrical potential difference across the membrane.

An easy way to remember this is that electrogenic refers to the pump's ability to generate electricity, similar to how a battery works. A sodium potassium pump 'generates' an electrochemical gradient, which is a form of potential energy that cells can use for various functions.

If the density of ocean water at a depth of 1.00 x 104 m is 1.071 g/ml and if 21.0 g of water at that depth contains 197 mg of potassium chloride, what is the molarity of potassium chloride in the sample

Answers

Final answer:

To find the molarity of potassium chloride in the given sample, calculate the volume of water using the density,then determine the molarity by dividing the number of moles of potassium chloride by the volume of water.

Explanation:

To find the molarity of potassium chloride in the given sample, we need to calculate the number of moles of potassium chloride in 21.0 g of water at a depth of 1.00 x 10^4 m.

We know that 1.071 g/mL is the density of ocean water at that depth. Since we have 21.0 g of water, we can calculate the volume of water using the formula: volume = mass / density.

Once we have the volume of water, we can determine the molarity of potassium chloride by dividing the number of moles of potassium chloride by the volume of water.

The molarity of potassium chloride in the ocean water sample at a depth of 1.00 x 10⁴ m is approximately 0.135 M.


We used the given sample mass, KCl content, and density to perform the calculation

The key steps included converting measurements, finding moles, and determining molarity.To determine the molarity of potassium chloride (KCl) at a depth of 1.00 x 10⁴ m, we follow these steps:

Calculate the volume of the seawater sample:

The sample weight is 21.0 g and the density is 1.071 g/mL. Volume = Mass / Density, So , Volume = 21.0 g / 1.071 g/mL ≈ 19.61 mL.

Convert the volume to liters:

19.61 mL * 1 L / 1000 mL = 0.01961 L.

Determine the mass of KCl in grams:

The sample contains 197 mg of KCl, which is 0.197 g.

Calculate the number of moles of KCl:

Molar mass of KCl is approximately 74.55 g/mol. Moles of KCl = 0.197 g / 74.55 g/mol ≈ 0.00264 mol.

Calculate the molarity of KCl:

Molarity (M) = Moles of solute / Volume of solution in liters, So, M = 0.00264 mol / 0.01961 L ≈ 0.135 M.

Therefore, the molarity of potassium chloride in the sample is approximately 0.135 M.

Explain how a redox reaction involves electrons in the same way that acid-base reaction involve protons

Answers

Final answer:

Redox reactions involve the transfer of electrons from one molecule to another, specifically from an oxidizing agent to a reducing agent. Likewise, acid-base reactions involve the transfer of protons from acid to a base. Thus, both types of reactions fundamentally operate on the principle of particle transfer.

Explanation:

In both redox reactions and acid-base reactions, the key component that leads to a reaction are the transfer of certain particles. For redox reactions, these particles are electrons, and for acid-base reactions, these particles are protons (H+ ions).

In a redox reaction, reduction and oxidation occur simultaneously. This means that one element or compound will lose electrons (oxidation) and another will gain those lost electrons (reduction). These reactions are therefore referred to as electron-transfer reactions.

Conversely, in an acid-base reaction, an acid donates a proton (H+) to a base which accepts it. Like electrons in a redox reaction, the proton in an acid-base reaction is transferred from one molecule to another.

So, the way a redox reaction involves electrons is similar to how an acid-base reaction involves protons - both involve the transfer of particles, although the specific particle transferred differs.

When a strontium atom loses two electrons, it becomes a(n) _____ with a charge of _____?

Answers

When a strontium atom loses two electrons, it becomes a(n) cation with a charge of 2+.
when any neutral atom loses an electron it becomes cation that is positively charged ions and an ion gets the charge according to the number of electrons loses. And if an atom gains an electron it becomes anion that is negatively charged ions.

When a strontium (Sr) atom loses two electrons, it becomes a cation with a charge of +2.

Here's a step-by-step explanation:

Atomic Number and Electrons: A neutral strontium atom has an atomic number of 38, which means it has 38 protons and 38 electrons.

Losing Electrons: When strontium loses two electrons, it now has 36 electrons (38 original electrons - 2 lost electrons).

Resulting Ion: The atom now has 38 protons (positive charge) and 36 electrons (negative charge), resulting in an overall charge of +2 because there are two more protons than electrons.

Type of Ion: Since it has a positive charge, it is a cation.

Chemical Symbol for the Ion: The symbol for the ion is written as Sr²+.

Therefore, when a strontium atom loses two electrons, it becomes an ion with a charge of +2.

Answers

Refer to the diagrams shown below.

Goal:
We want to determine the amount of heat required to convert 59 g of ice at  -35 °C to liquid water at 55 °C.

Given:
c = 2.09 J/(g-°C), the specific heat of ice
   = 4.18  J/(g-°C), the specific heat of water
   = 2.03 J/(g-°C), the specific heat of steam

L = 334 J/g, the latent heat of fusion of water
   = 2260 J/g, the latent heat of vaporization of water 

Stage 1: Convert ice at  -35 °C to ice at 0 °C.
The heat required is
Q₁ = (59 g)*(2.09 J/(g-°C))*(0-(-35) °C) = 4,315.85 J

Stage 2: Convert ice at 0 °C to water at 0 °C.
The heat required is
Q₂ = (59 g)*(334 J/g) = 19,706 J

Stage 3: Raise the temperature of the water from 0 °C to 55 °C.
The heat required is
Q₃ = (59 g)*(4.18 J/(g-°C))*(55 °C) = 13,564.10 J

The total heat required is
Q = Q₁ + Q₂ + Q₃ = 37,585.95 J = 37.586 kJ

Answer: 37.6 kJ

The total heat required is 37.60 kJ.

To calculate the amount of heat required to convert 59 g of ice at -35°C completely to liquid water at 55°C, we need to consider several steps: heating the ice, melting the ice, and heating the liquid water.

Heating the ice from -35°C to 0°C:
q₁ = mass x specific heat of ice x temperature change
q₁ = 59 g x 2.09 J/g°C x (0 - (-35))°C = 59 g x 2.09 J/g°C x 35°C = 4313.15 JMelting the ice at 0°C:
q₂ = mass x heat of fusion
q₂ = 59 g x 334 J/g = 19706 JHeating the liquid water from 0°C to 55°C:
q₃ = mass x specific heat of liquid water x temperature change
q₃ = 59 g x 4.18 J/g°C x (55 - 0)°C = 59 g x 4.18 J/g°C x 55°C = 13584.10 J

Summing these three quantities gives the total heat required:

Total heat (q total) = q₁ + q₂ + q₃
q total = 4313.15 J + 19706 J + 13584.10 J = 37603.25 J

To convert this into kilojoules (kJ), we divide by 1000:

37.60325 kJ ≈ 37.60 kJ

Therefore, the heat required is 37.60 kJ.

the correct answer is temperature

Answer: The correct answer is temperature.

Explanation:

The solubility is defined as the amount of solute that can be dissolved in a given amount of solvent at specific temperature.

We are given that the solubility of NaCl is 35.9g per 100g at 20°C.

If we dissolve 35.9 grams in 100 grams of water, it is completely dissolve at this temperature.

If the temperature increases, the solubility also increases and if temperature decreases, the solubility decreases.

It is given that some solid remains undissolved, so the temperature would have been decreased, therefore the solubility decreases.

Hence, the correct answer is temperature.

A radioactive substance used in nuclear weapons decays at the rate of 3.33.3​% per year. calculate the​ half-life of the radioactive substance.

Answers

Final answer:

The half-life of the radioactive substance, undergoing decay at a rate of 3.33% per year, is approximately 20.87 years. This means that it takes around 20.87 years for the substance to reduce to half of its initial quantity due to radioactive decay.

Explanation:

Radioactive decay follows an exponential decay model, which can be expressed using the formula:

[tex]\[ N(t) = N_0 \times (1 - r)^t \][/tex]

Where:

[tex]- \( N(t) \)[/tex]is the quantity of the substance at time [tex]\( t \)[/tex],

[tex]- \( N_0 \)[/tex] is the initial quantity,

[tex]- \( r \)[/tex] is the decay rate per unit time, and

[tex]- \( t \)[/tex] is the time elapsed.

In this case, the decay rate [tex](\( r \))[/tex]is given as 3.33%, or 0.0333. To find the half-life [tex](\( T_{\frac{1}{2}} \)), we set \( \frac{N(t)}{N_0} = \frac{1}{2} \)[/tex]and solve for[tex]\( t \)[/tex]:

[tex]\[ \frac{1}{2} = (1 - 0.0333)^t \][/tex]

Taking the natural logarithm of both sides:

[tex]\[ \ln\left(\frac{1}{2}\right) = t \times \ln(1 - 0.0333) \][/tex]

Solving for [tex]\( t \)[/tex] gives us the time required for the substance to decay to half its initial quantity. The result is approximately 20.87 years.

This means that after 20.87 years, the quantity of the radioactive substance will have decreased to half of its initial amount. This exponential decay is a fundamental characteristic of radioactive substances and plays a crucial role in various scientific and practical applications, including the estimation of radioactive waste decay and the determination of the age of archaeological artifacts using radioactive dating techniques.

Lewis structure of [tex]{\mathbf{C}}{{\mathbf{H}}_{\mathbf{3}}}{\mathbf{SSC}}{{\mathbf{H}}_{\mathbf{3}}}[/tex] (Refer to the structure in the attached image):

The total number of valence electrons of [tex]{\text{C}}{{\text{H}}_{\text{3}}}{\text{SSC}}{{\text{H}}_{\text{3}}}[/tex] is calculated as follows:

Total valence electrons = [(2) (Valence electrons of C) + (2) (Valence electrons of S) + (6) (Valence electrons of H)]

In [tex]{\text{C}}{{\text{H}}_{\text{3}}}{\text{SSC}}{{\text{H}}_{\text{3}}}[/tex], the total number of valence electrons is 26. In this molecule, each carbon forms three single bonds with three discrete hydrogen atoms and one single bond with sulfur atoms.

Functional groups attached to a benzene ring can be either electron withdrawing, electron donating, or neither. Electron withdrawing groups deactivate the ring and increase acid strength, while electron donating groups activate the ring and decrease acid strength. Some groups, like alkyl, are neutral with minimal effects.

Effect of Functional Groups on the Benzene Ring:

In order to determine whether a functional group attached to a benzene ring is electron withdrawing, electron donating, or neither, we need to consider both inductive and resonance effects:

Electron Withdrawing Groups:

Functional groups like -NO₂ (nitro), -CF₃ (trifluoromethyl), and -SO₃H (sulfonic acid) are classified as electron withdrawing. These groups deactivate the benzene ring towards electrophilic attack and increase the acidity of benzoic acids. This is due to their ability to pull electron density away from the ring both via inductive effects and resonance.

Electron Donating Groups:

Groups such as -OH (hydroxyl), -NH₂ (amino), and -OCH₃ (methoxy) are electron donating. These substituents activate the benzene ring towards electrophilic attack due to their ability to donate electron density to the ring through resonance, thus decreasing the acidity of benzoic acids.

Neutral Groups:

Some groups, such as alkyl groups (-CH₃), do not have significant electron withdrawing or donating effects. These groups neither significantly activate nor deactivate the benzene ring.
